Assieivon ro SOCIT ANO- NYME: GRAISSAGE AI-CYLW OF LEVALLOIS-PERRET, SEINE, FRAN APPARATUS FOR LUBRICA'IION `:BY MEANS 0F CAPILLARY ELEMENTS Ap'plgcrfitionA filed May 24, 1928,` Seriali-No. 280,283, and in France June 2, 1927.

*It has been specified in the United States patent application SerialNo. 159,702 that the lubricating ducts were terminated by a thimble or junction piece permitting to connect them together or to couple them to the pointsv to be lubricated, such ducts containing a capillary member having the forni of a wick or cord of greater or less'thicl'rness.

In the description of the United States patent application Serial No. 159,702 the said wick was held in the thimble by means of a knot plac-ed upon the horizontal part of a small recess which is milled in the body of tlie said thimble.

It was stated in the French patent of addition No. 32,823 Vof the 10th of January, 1927, that the said device could be'replaced by a small stopping piece which is pressed upon the wick after the manner ofthe tag of a shoe lace, for instance, j

The said stopping piece was then held by crimping in the thiiiible; a slight deforma tion of the latter maintains it in placev and prevents the wick from escaping into the interior ofthe tube or fromissuing at the eX- f terior of the thimble.

The present improvement relates to another method of fastening .by which the said wick is held in the tliimble by the crimping process. Y, L

A suitable slot is milled in the said thimble Y and theV crimping properly so `called is effected by a Vtool of suitable shape whichcauses the deformation of the metal of the edges of the milled part, and thus crimps tlielatter upon the wick which is situated in the bottom of the slot.

The following description with reference way of example sets forth the manner in which the said invention is carried into effect.

Figure 1 is a front elevational view of the coupling thimble, the right hand part of the ligure being shown in section on the line X-X of Figure 3.

Figure 2 is aside elevation corresponding to Figure 1 and partly in section.

F iOjiire 3 is a plan View partly' in section. onVV the line Y- -Y of Figure 1.

`serves for the lubrication is placed in a slot 1 which is formed in the interior of the thinible; when the said wick has assumed the .properposition the edges of the slot 1 are driven inwardly, as shown for example at 2, by means of a suitable tool, so that the wick will be pressed and held in its recess. The projecting `end is then cut oil', and the wick will thus be properly-secured imposition.

What I claim is z*V y l. A coupling device for capillary lubrieating systems comprising an internally grooved thimble having anl inlet orifice communicating with said groove, a flexible capillary elemeiit disposed in said orifice exteiiding into said groove,and a pair of integral retaining lugs formed on said tliimble adjacent said groovefor retaining said capillary element in said groove.

2. A coupling device for capillary'lubrieating systems comprising an internally 1 ,grooved thimble having an inlet orifice communicating with said groove, a flexible capillary element disposed in said orifice eX'- tendiiig into said groove, anda plurality of pairs of integral retaining lugs formed on said thimble adjacent said groove for retaining said capillary element in said groove. Y

3. A' coupling device for capillary lubricating systems comprising an internally grooved thimble-haviiig an inlet orificeccminunicating with said groove, a wick disposed in said orifice `ei'rtendiiig into said groove, and a pair Voli-integral retaining lugs formed on said thiiiible adjacent said groove l foriretaininffsaid wick in said Groove. 40 to the appended drawingswhich are given by t 1 b 4.
